We demonstrate the use of 2D-selective excitation with parallel transmission to (a) simultaneously perform BOLD fMRI on two apart brain regions, and (b) benefit from high acceleration factors achievable with sparse volume excitation. Using 8ch pTX at 7T, we apply spatially selective pulses to excite the primary motor and sensory cortices, as well as cerebellum. tSNR measures confirm superior performance compared to whole-brain excitation at the same TR. A finger tapping task is used to elicit digit-specific activation, which is observed in primary cortex and cerebellum.
